exim configuration files wrong group name

the configurations files for exim located at /etc and /etc/valiases and /home folder has a wrong group, it must be username:mail but instead it is username:game this is causing me several problems because emails are not been sended. All emails, incoming and outgoing has been rejected, exim_mainlog returns this error: temporarily rejected RCPT : failed to open /etc/valiases/domain.mx for linear search: Permission denied (euid=47 egid=8) I already executed the script /scripts/mailperm and only fixes the permissions on /home directory I did change the files' group on /etc with this line: find . -group games -exec chown root:mail {} \; and change manually the group for valiases to mail but in a question of time the group has been changed again to games. I already forced the cpanel update with /scripts/upcp --force and still the same, please help!
